Fantastic. Somewhere between Dickens, Sherlock Holmes and Rider Haggard. I was in seventh heaven

A page-turner, a rollicking ride . . . stupendous

A novel of desire, sensation and desperate jeopardy . . . genuinely exciting and intriguing

An erotically charged, rip-roaring adventure for adults with scarcely a dull moment to be had . . . keep[s] the reader on the edge of his seat

What’s right with it? You’ll fall in love with the characters. They’re kind, anxious, flawed, funny and wonderful. Also, knowing that the two stories will have to meet builds a wonderful sense of tension. What’s wrong with it? Nothing. It’s brilliant. Even the fact that Byron is convinced that scientists tried to slip an extra two seconds into time is a wonderful hook for all the decisions he goes on to make. Verdict: Uplifting, engaging, sad and funny. A perfect follow-up to The Unlikely Pilgrimage of Harold Fry.

This book is hard in every sense... But persevere and plough on alongside Byron (who you’ll find you want to stay with, as if by continuing to read him you might be able to protect him somehow, or at least keep him company), and the reward is a redemptive ending of such tenderness that after 300-odd pages of darkness you will end up grinning dippily and recommending this wild, searching book to everyone you know.

Brilliantly realized... a powerful study of grief, loss, guilt, depression, mental illness - and ultimately the power of love - which grips the reader on every page.

Colonising the territory occupied by Catherine O'Flynn and Clare Morrall, Perfect is marked by effortless storytelling, droll side-swipes at the oddities of human behaviour and the use of simple, unaffected imagery that manages to plumb deep emotion... it will move and enchant.

This month's best book. 3 reasons to read Perfect: for real characters you'll fall in love with... for a book that will keep you asking questions... to question the nature of mistakes.

Full of compassion... the heartbreaking story of how two lives are derailed by a split-second mistake.

A compelling novel about the crushing restrictions that class and gender can impose, the burden of parental expectation, and the stigma attached to mental illness.

[Joyce] is a charming and skilful writer

The language [Joyce] uses is really poignant and evocative. It is so beautiful and well-crafted I didn't want it to end.

Unforgettable... a deft and original follow-up to The Unlikely Pilgrimage of Harold Fry

The author of last year's biggest selling debut The Unlikely Pilgrimage of Harold Fry returns with a very different but equally captivating novel... This is a heartbreaking story, full of compassion, that unfolds gently but relentlessly against the backdrop of the suburban '70s. Perfect confirms [Rachel Joyce] as a major new voice.

Moving, insightful and satirical

Joyce’s last novel The Unlikely Pilgrimage Of Harold Fry was a wonderful story of an older man walking across England to say goodbye to a dying friend. It was spoken of fondly in book clubs and in reviews and longlisted for the Man Booker Prize. In Perfect, Joyce has created an excellent follow up.

A cleverly-plotted tale, it is moving yet unsentimental. Sure to delight Joyce fans who made The Unlikely Pilgrimage of Harold Fry a best-seller.

With Perfect, Joyce wrings another rewarding tale out of the little tragedies of life

Rachel Joyce's first novel, The Unlikely Pilgrimage of Harold Fry, won both commercial success and wide critical acclaim (it was longlisted for the Man Booker Prize). She may just repeat the trick with Perfect, a mixture of comedy and drama in much the same vein... this is a novel with the capacity to both surprise and charm.

Out of the smallest, most delicate building blocks, Rachel Joyce gradually builds a towering sense of menace. She understands people, in all their intricacy and vulnerability, in a way few writers do. Perfect is a poignant and powerful book, rich with empathy and charged with beautiful, atmospheric writing.

Intriguing and suspenseful... Joyce, showing the same talent for adroit plot development seen in the bestselling The Unlikely Pilgrimage of Harold Fry, brings both narrative strands together in a shocking, redemptive denouement.

[Joyce's] sympathetically realised characters are people living on the edge, whether of loneliness, poverty or mental illness, and despite its underlying sadness, the book ends with the presage of hope.

A moving and original novel... it confirms [Joyce] as one of the most interesting voices in British fiction

A rewarding, multi-layered novel with empathy for disturbed mental states and, towards the end, a clever fast-forwarding 30 years.

Rachel Joyce's new novel is simply Perfect.

[Joyce] triumphantly returns with PERFECT…As Joyce probes the souls of Diane, Byron, and Jim, she reveals – slowly and deliberately, as if peeling back a delicate onion skin – the connection between the two stories, creating a poignant, searching tale.”

In alternating chapters, these two stories set 40 years apart frame Joyce’s exquisitely played novel of tragedy and mental illness and the kind of wrenching courage unique to those who suffer from the latter and yet battle to overcome it. As in her brilliant debut, The Unlikely Pilgrimage of Harold Fry, Joyce stuns with her beautifully realized characters and the unexpected convergence of her two tales.

Perfect touches on class, mental illness, and the ways a psyche is formed or broken. It has the tenor of a horror film, and yet at the end, in some kind of contortionist trick, the narrative unfolds into an unexpected burst of redemption. Buy It.

Joyce flings “Perfect’s” characters into chaotic situations fraught with misgivings and confusion ... Diana’s descent into terror is provocative enough to carry this story, but Joyce complements it with a contemporary one about an equally fragile man named Jim who has spent most of his life in a facility for the mentally ill. His connection to Diana will surprise many readers as Joyce spins this equally compelling subplot toward its shocking revelations and conclusion.

Better than The Unlikely Pilgrimage of Harold Fry... touching [and] eccentric.

Ambitious, dark and honest

That [Perfect] is unputdownable lies in its exploration of so many multilayered emotions. There is the unbreakable bond between mother and son, ?the fear of not belonging, loneliness, grief, guilt, depression, loss, the destructive nature of mental illness and how love can offer redemption.It has been a long time since a novel made me cry, but Joyce’s prose forced those tears out in the closing chapters. It is her clever did-I-read-that-right twist at the end that really got to me and had me scrabbling back though the chapters, open-mouthed.
